BENJAMIN S. HYERS, OF PEKIN, ILLINOIS.

IMPROVEMENT IN SELF-OILING CUPS FOR AXLE-BOXES.

Specification forming part of Letters Patent No. 154,487, dated August 25, 1874: application filed May 27, 1874.

To all whom it may concern.-

Be it known thatI, BENJAMIN S. Evans,

of the city of Pekin, in the county of Tazewell and in the State of Illinois, have invented a Self-Oiling (Jup for Axle-Boxes, or any wheel 'which revolves upon an axle; and do hereby 3; Fig. 3, a vertical section along line a a a a,

Fig. 1.

' The object of this invention is to provide a lubricating device to revolve with the axle-box of any wheel, pinion, pulley, or other similar mechanism, which revolves upon an axle or shaft, which cup, being reversed at every revo lution, oils the axle-box and shaft.

7 To do this I provide a cup, C,having a lower opening, which may be pointed so as to sit upon a gasket or elastic cushion, e, of an annular form, resting in a socket, f, in the axle-.

box B of any wheel or pulley above the entrance to an oil-duct, d, which leads down to the axle or shaft. The cup may, when the wheel is small, as a car-wheel or pulley, be retained within said socket by having its upper end held within a groove or slot, orother recess, in the inner periphery of the rim, and be securely fastened by a wedge, 11, placed between said cup top and the ceiling of such groove or slot, in such a manner as will allow of access to an oil-charging opening, 9, in the side of or top of the cup; also, allowing the cup to be removed for the same purpose by taking out the wedge or removing a set-screw, which I use with equal effect.

To prevent too great a flow of oil when the cup is reversed by the revolution of the axlebox, the cup is filled with wicking or other suspending substance. The cup is firmly pressed down upon the gasket 0 by means of the wedge i, leaving no chance for the escape of oil.

In a small wheel the cup 0 is set in its socket in the axle-box B, so as to incline inward, its upper end being retained in the above-mentioned inclined groove k, with the wedge i, and prevented from turning by means of the provision of a square recess on either side of the groove or slot k, into which the corresponding shoulders I) of the head or top of the cup fit. A thumb-screw or set-screw may also be used, instead of the wedge, to abut upon the head of the cup from the side of the inclined recess.

What I claim as my invention is-- 1. An axle-box oil-cup provided with side .opening g, shoulders or detents bat thettop,

in combination with a wedge, t, and inclined groove is, or recess cut or formed in the inner surface of the rim of a wheel or pulley, for the purpose of wedging the tapering lower end of the cup into a recess, f, over an oil'duct, d, in an axle-box, B, substantially as and for the pur-I;

poses specified.

9. The combination of the duct d, recess f, cushion 6, cup 0, head h, wedge 6, slot or recess k, and rim m, substantially as described.

In testimony that I claim the foregoing selfoiling axle-box cup I have hereunto set my hand this 18th day of May, 1874.
